The Empirical Rule states that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. Under this rule, 68% of the data falls within one standard deviation, 95% percent within two standard deviations, and 99.7% within three standard deviations from the mean.
f(-2) is the x value, fond the Y value of the graphed line when the line is at x -2.
The line is at Y = 2
The answer is B.
Hello there!
The slopes of perpendicular lines are opposite reciprocals. It means we take the slope of the given line, flop it over and make it negative.
And then just plug in the points:
y-y1=m(x-x1)
y-3=-1/4x-(-5)
y-3=-1/4x+5
Hope this helps!

The area of the window is about 42.39 square feet
1 feet =12 inches
And 6 inches = 1/2 feet
13 1/2*3.14=42.39 feet²
The area of the window is about 508.68 square inches
1 feet =12 inches
And 13 feet*12= 156 inches
156 inches + 6 inches = 162 inches
Then, 162*3.14=508.68 inches²
